• Seams – longitudinal or horizontal cross-

sections where insulation meets and must be

adhered to itself or other system components.

• Butt Joints – cross-sections where two pieces

of tubular or sheet insulation must be adhered

to itself or other system components.

• Vapor (Water) Stops – locations/methods to

prevent water or water vapor from traveling

from one pipe insulation section to an adjacent

insulation and prevent water traveling down

annular space between the pipe insulation and

the tubular pipe.

• Sleeving/Multi-Layering – applying another

layer of insulation over the first layer. This

process is used when the insulation thickness

required is greater than that which is

commercially available. This technique is also

employed when proper installation practice

requires multiple layers and or staggered joint

application, even if a single layer thickness is

available.

adhesive from thickening. Stir frequently to

prevent activators from settling to bottom.

Note: Do not use adhesives when relative

humidity is 100% due to the formation of

condensation on substrates.

Aerocel EPDM Insulation 1. Storage: store Aerocel insulation at 40°F - 100°F

[4°C - 38°C] prior to installation. Cold closed

cell elastomeric foam insulation will lose its

flexibility. Keep dry.

2. Pressure-Sensitive Adhesive (PSA): SSPT

tubes, Cel-Link II, Sheet & Roll with PSA,

Protape and Aerotape should be installed when

substrate and ambient temperatures are above

50°F [10°C]. At temperatures between 0°F - 50°F

[4°C - 10°C], significant pressure must be applied

to achieve an adequate bond. Installation of PSA

products below 40°F [4°C] is not recommended.

Pinch corner and pull release liner back 6" - 10"

[15 cm - 25 cm] at a time during installation.

For sheets/rolls, use weighted roller to achieve

complete contact.

BEST PRACTICESSubstrate Preparation - Never insulate a system in operation. Turn off

system 24 hours prior to installation to avoid

moisture development under insulation, potential

corrosion under insulation (CUI) and adhesive

failure. Follow Aerocel adhesive complete dry

times prior to system start-up.

- Clean substrates with denatured alcohol.

Remove dirt, dust, grease, moisture, oil and

other contaminants that can serve as corrosion

accelerators beneath the insulation and bond-

breaking agents on direct-adhered adhesive

applications.

- Untreated steel surfaces must be treated with a

rust inhibitor for HVAC/R applications. Follow the

rust inhibitor manufacturer’s full cure time prior

to installing Aerocel.

- Corrosion Protection Primers: test Aerocel

adhesive for compatibility with epoxy resin

and polyurethane primers. Adhesives are not

compatible with asphalt, bitumen, linseed oil or

red lead primers.

- Recommended application temperature range

(substrates and ambient) is 40°F - 100°F [4°C -

38°C].

- Cold weather installation: cold substrates will

prolong flash time of adhesives. When conditions

are below 40°F [4°C], adhesive bonded to very

cold substrates may not flash off at all due to

formation of condensation from latent heat of

adhesive. Adhesive container can be warmed in a

bucket of hot water. Adhesive container opening

should be covered with a Aerocel sheet insulation

or cardboard cut-out with brush hole to prevent

adhesive from thickening. Stir frequently to

prevent activators from settling to bottom.

- Hot weather installation: heated substrates

will cause adhesive to flash off very quickly. If

adhesive is left open beyond flash time, adhesion

will not occur. Adjust by applying adhesive to

smaller areas. Adhesive container opening should

be covered with a Aerocel sheet insulation or

cardboard cut-out with brush hole to prevent

5. Push, Never Pull (Stretch) Insulation

6. Spacing: allow a minimum of 4” [10 cm]

between insulated chilled water and

refrigeration pipes to allow for air movement to

prevent condensation.

7. Seams, Butt Joints & Termination Points:

completely seal with Aerocel adhesive to create

vapor seal in order to prevent air and moisture

from penetrating under the insulation and

causing corrosion under insulation (CUI). Seal all

cut-outs and termination points, such as flanges,

3. Sizing: properly sized pipe insulation tubes

should slide easily over the pipe and fittings.

Aerocel ID’s are designed to properly fit copper

and iron piping. A tube that fits loosely over

a pipe is better than a smaller size that is too

snug. Never stretch Aerocel insulation. An air

gap between the pipe and insulation (annular

space) is acceptable provided that all seams are

completely sealed with an Aerocel adhesive.

When measuring sheet material, mark where the

adjoining edges overlap.

Note: Although Aerocel SSPT tubes are

available up to 16” IPS, Sheet & Roll can be

used on pipe sizes ≥4” [10 cm] OD.

4. Cutting: use sharp non-serrated knives. Knife

should be maintained at low angle to prevent tip

from cutting/slitting inside wall. Cut flattest side

of tube. Measure and cut all lengths (tube and

sheet) long +1/8” [.32 cm] on each side (1/4”, .64

cm) to install under compression. Use sharpened

pipe cut-offs for holes. Glued seams should

never be stretched and under stress.

was dry to the touch prior to contact. For

exterior applications, taping all glued seams

with Protape is required; turn taped longitudinal

seams away from direct sun exposure when

possible.

• Note: Protape should never be installed over

a seam that is not sealed with an Aerocel

adhesive or Cel-Link II.

Cel-Link II Glueless Seam Seals - Cel-Link II glueless seam seals, Aeroflex squeegee

and instructions are included with every carton of

Aerocel SSPT pipe insulation.

- Install Cel-Link II over pipe and between adjoining

tubes.

- Peel seam seal from release liner.

- Apply exposed adhesive side of Cel-Link II to

one tube and thoroughly compress to maximize

adhesion.

- Peel gold release liner to other side of seam seal

facing adjoining tube and align longitudinal seams.

- Press adjoining tubes together under

compression.

- Apply 2” Protape evenly over all butt joints

(required).

supports and valves, with Aerocel adhesive.

Note: Never use zip ties as substitute for

adhesive; zip ties do not seal and they

compress the insulation.

8. Vapor Stops: for below-ambient (cold)

applications, adhere the tube or sheet insulation

directly to the pipe a maximum of every 18

linear feet [5.5 m]. The adhesive width should be

at a minimum equal to the insulation thickness.

Protape wrapped around the pipe can be used

as vapor stop in place of adhesive. Seal butt

joints with Aerocel adhesive or Cel-Link II for

SSPT installations.

9. Taping Seams: applying zero-perm Protape

over sealed seams for interior applications

is recommended as an additional level of

protection to prevent CUI. For pipe sizes over

6" IPS [15 cm] and sheets/rolls over 1" thick [2.5

cm], apply 2" [5 cm] Protape evenly over seams

TIP - Use the “fingernail test” to determine when

tack time has been achieved; touch the glued

surface with fingernail; if fingernail sticks and

glue transfers, the adhesive is not ready; if the

fingernail does not stick, there is no glue transfer

and adhesive is either dry to the touch (Aeroseal

and Aeroseal LVOC Black) or tacky (REF 1520),

the two glued surfaces are ready for contact.

- Apply thin even coat to both surfaces to be sealed

with a short stiff-bristle brush from the inside out

(tubes) or with an adhesive/short-nap roller for

sheets and rolls.

- Brush adhesive on approximately 7” [18 cm] on

one surface, then 7” [18 cm] on the other surface,

alternating back and forth until longitudinal seam

is glued; once adhesive is ready for contact, press

both surfaces together under compression to

ensure full adhesion.

- Avoid stretching and tension at glued seams.

- When applying to surfaces other than insulation

(i.e. metal termination points), apply adhesive to

Aerocel insulation first, then the other surface.

- For applications over concrete substrates, consult

with Aeroflex USA.

- For exterior applications, turn glued seams away

from sun when possible.

- Use acetone to clean tools.

AeroFit Fitting Covers

- AeroFit fitting covers ship unslit.

- When fittings and straight runs are same size,

install fittings first followed by straight sections.

- When fittings are larger than straight runs

(oversized), install straight runs first.

- Slit inside radius of fitting (throat) with sharp

knife.

Aerocel Adhesives

- Read label and follow warnings; work area should

be well-ventilated; do not smoke.

- Do not thin adhesives.

- Substrates, ambient temperatures and adhesive

should be 40°F - 100°F [4°C - 38°C].

- Do not use below 40°F [4°C].

- Store at 60°F - 80°F [16°C - 27°C].

- Do not allow to freeze.

- Cold adhesive containers can be warmed in

bucket of hot water.

- Stir thoroughly before use and frequently during

use.

- For non-brush top containers, use a Gluemaster

or cover opening with Aerocel sheet insulation

or cardboard cut-out with brush hole to prevent

adhesive from thickening.

- Follow tack time on label and adjust based on

jobsite conditions – ambient temperature, relative

humidity and wind.

- Aeroseal and Aeroseal LVOC Black adhesives

must be dry to the touch (no transfer) prior to

contact to ensure immediate adhesion and a

permanent bond.

- REF 1520 adhesive must be tacky (no transfer)

prior to contact to ensure a permanent bond.

- Aeroseal LVOC Black adhesive requires a

longer tack time than Aeroseal or REF 1520;

allow 3-5 minutes depending on ambient

conditions during installation. LVOC adhesive

must be dry to the touch (no transfer) prior to

contact to ensure immediate adhesion and a

permanent bond.

Aerocel with SaniGuard

- Outer surface temperature of Aerocel

insulation must be continuously maintained

below 150°F [65°C].

- Follow best practices to install Aerocel unslit

tube, SSPT tube and AeroFit fitting covers.

- SaniGuard PVC jacket sections are included in

carton with 3-foot [.91 m] Aerocel unslit tube or

SSPT pipe insulation. AeroFit 90° long-radius

elbows, SaniGuard White 2” [5 cm] PVC Tape and

welding adhesive are sold separately.

- SaniGuard sections are intentionally 2” [5 cm]

longer than the insulation tubes to ensure an

overlap at SaniGuard seams. When cutting

SaniGuard, add 2” [5 cm] to all measurements.

- When applicable, install AeroFit fittings first

followed by straight pipe runs.

- Ensure that all longitudinal seams, butt joints and

termination points of insulation are sealed with an

Aerocel adhesive or Cel-Link II and covered with

Protape prior to installing the SaniGuard jacket.

- Carefully install SaniGuard jacket over sealed

Aerocel insulation to prevent surface damage.

- Position longitudinal overlap of SaniGuard jacket

downward to allow watershed and position out of

sight line.

- Prior to sealing seams, fit SaniGuard jacket tightly

to outer surface of Aerocel insulation leaving no

gaps.

- Seal the SaniGuard overlaps with pressure-

sensitive adhesive release liner located on inside

of jacket; peel, seal and apply firm pressure to

ensure complete adhesion.

- Once a sufficient amount of jacketing has been

- Install over pipe fitting to ensure proper fit - snug

or slightly loose (not stretched).

- Apply adhesive to both sides of radius seam; allow

to tack up and press together under compression

to ensure full adhesion and vapor seal.

- When bonding fitting covers to straight runs of

pipe insulation, allow adhesive to tack up and

press together under compression to ensure

complete adhesion and vapor seal.

- Optional: for interior applications, apply Protape

over glued seams.

- Required: for exterior applications, apply Protape

over glued seams; turn taped longitudinal seams

away from direct sun exposure when possible.

conduit, such as a fully-supported and sealed

waste-water drainage pipe, to ensure long-term

performance once backfilled.

- Direct contact with soil acids, ground water

chemicals, contaminants, plus insulation

compression from the weight of the backfilled

soil, can reduce the thermal efficiency and life of

the insulation.

prolong the life of

Aerocel. Options include

Aerocoat, Aerocoat

LVOC or an insulation

jacketing system. When

mechanical damage,

such as impacts from

maintenance, extreme

weather, birds, etc.

are expected, Aerocel

should be protected with a jacketing system.

- For pipe sizes over 6" IPS and sheets/rolls over

1" thick, apply 2" Protape evenly over seams

followed by 2" on either side of taped seam (4"

[10 cm] total taped seam width).

• Note: Aerocoat and Aerocoat LVOC satisfy

• Notes:

- Full coverage adhesion of sheets/rolls

to pipes is not recommended due to

variation of expansion/contraction by

layer on an operational system.

- Prior to sealing butt joints on chilled water

or refrigerant piping, install vapor stop at

all butt joints by applying at least 1/2” [1.3

cm] strip of adhesive to pipe and insulation

bonding insulation directly to the pipe.

- To minimize sagging on vertical piping,

apply wide (approx. 4” [10 cm]) adhesive

strips to pipe and insulation at all butt joints

and directly adhere insulation to the pipe.

- For pipe sizes ≥12” [30 cm] OD, sheets/

rolls should be directly adhered to bottom

1/3 of the pipe to prevent sagging.

- Multi-Layering

• Ensure that outer skin of first layer is dry

and dust-free; clean with denatured alcohol if

necessary.

- Note: If Aeroseal or Aeroseal LVOC Black

were installed with 1st layer and dry to the

touch prior to contact, the 2nd layer may be

applied immediately. For REF 1520, allow 24-

36 hours cure time for 1st layer.

• Measure outside diameter of 1st insulated layer

by applying the same principles when

measuring pipe OD for 1st layer.

Conditions”) and limitations (the “Warranty Limitations”) appearing below in this Express Limited Warranty

Information and provides solely the remedy (the “Exclusive Remedy for Valid Warranty Claim”) to the Buyer as

listed below.

THIS EXPRESS LIMITED WARRANTY CONSTITUTES THE ENTIRE OBLIGATION OF SELLER AND THERE ARE

NO OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY,

WARRANTY OF FITNESS FOR ANY PURPOSE WHATSOEVER OR WARRANTY OF FITNESS FOR A PARTICULAR

PURPOSE; SELLER HEREBY DISCLAIMS ALL IMPLIED WARRANTIES OF ANY TYPE OR SORT, INCLUDING

WITHOUT LIMITATION: (1) THE IMPLIED WARRANTY OF MERCHANTABILITY, (2) THE IMPLIED WARRANTY

OF FITNESS FOR ANY PURPOSE WHATSOEVER AND (3) THE IMPLIED WARRANTY OF FITNESS FOR A

OF PROPERTY, PERSONAL INJURY, LOSS OF BUSINESS, LOSS OF PROFITS, OR ECONOMIC LOSSES) NOR FOR

PUNITIVE, STATUTORY, OR EXEMPLARY DAMAGES, WHETHER IN NEGLIGENCE, WARRANTY, STRICT LIABILITY OR

OTHERWISE.

This Express Limited Warranty shall not be modified, enlarged, expanded upon or affected in any way by verbal

commentary or non-written installation instructions or other advice by any person or entity, regardless of the

existence of a relationship of any type or sort between such person or entity and Seller; site specific and/or installation

conditions are not the responsibility of Seller or its representatives to address or provide advice and no verbal advice

by Seller or its representative concerning such matters shall constitute a warranty by Seller or alter the terms and

conditions of the Express Limited Warranty as set out in this Express Limited Warranty Information. Seller makes

no warranty, expressed or implied, with regard to the end-product manufactured by Buyer. Buyer, by purchasing the

Aerocel® Products, agrees that Buyer will not alter, amend or add to Seller’s Express Limited Warranty. If Buyer

desires to offer additional warranties or make any representation on its own, such warranties and/or representations

will clearly state that they are Buyer’s additional warranties and not those of Seller.

Warranty Limitations

The Aerocel® Products are manufactured and warranted for their thermal insulation performance hereunder solely

for use under normal conditions. Abnormal Conditions include exposure to certain chemical vapors, petroleum-based

substances, other substances and compounds not compatible with EPDM rubber products, INCLUDING WITHOUT

LIMITATION, petroleum oil and petroleum solvents such as Benzene, Gasoline, Kerosene, Octane, Toluene and Butyl

Acetate and the vapors of the same. Damage to the Aerocel® Products which may occur from fire, accident or any

form of abuse, or exposure to Abnormal Conditions is not covered by this warranty. While exposure to ultraviolet

light due to outdoor use is not considered Abnormal Conditions for purposes of this Express Limited Warranty,

cosmetic damage caused by outdoor use without additional weather protective coatings or coverings is not covered

by this Express Limited Warranty. Cosmetic damage due to uncovered or uncoated Aerocel® product exposed to

ultraviolet light for purposes of this warranty is considered any damage which does not affect the thermal insulative

properties of Aerocel® Products. All Aerocel® Products, including AeroFit™ fitting covers, used outdoors must

have Aerocel® Protape® EPDM rubber seam sealing tape applied to and covering all product seams, butt joints and

termination points to provide a vapor seal. If exposed or installed subject to Abnormal Conditions, the product

should be removed immediately and replaced once the conditions of installation are normal or with products more

suitable to general ambient conditions of the installation or installation site. The growth of mold is not covered by

this warranty nor is damage arising from the growth of mold the responsibility of Seller. All Aerocel® Products

should be maintained to avoid excessive dirt or dust buildup, or the presence of excessive moisture, that would

provide a medium for microbial growth on the Aerocel® Products.

Warranty Conditions

The above described Aerocel® Products each must be installed in accordance with Seller’s written installation

instructions for that product in effect at the time of installation and in accordance with best industry practice. Prior to

installation, the insulation product must be kept clean and dry and not subject to Abnormal Conditions. Installation of

the Aerocel® Products shall be installed when the ambient temperature is between 40°F (4°C) and 100°F (38°C) to

allow Aerocel® PSA insulation products and adhesives to properly tack and bond. The Express Limited Warranty is

void if improper installation practices or unapproved installation products are used. This Express Limited Warranty

does not extend to any component of the insulation system other than the specific Aerocel® Products identified

herein above, such as, but not limited to, adhesives other than Aerocel® adhesives, pinning devices, tapes other than

Protape® or Aerotape™, or any other accessory used in the installation of the Aerocel® Products.
